I know that it's easy to find 16x2 character LCD displays, 7 segment displays, and small monochrome displays (like old phone displays), but at least at the hobbyist level, it seems like you may as well go for the general-purpose color screen. Similar sized screens look like they're around the same price, regardless of if they're color or not.
